Since most of these reagents are pretty nasty or need
to be kept away from water, this chart will aid in transferring accurate
amounts of liquid by pipet or syringe (using the molarity of the reagent
given in the last column) with minimal exposure to the atmosphere (and
those you share the lab with).
